Serial Communications
SCANNER ID 1 – 247 (Scanner Modbus address)
BAUD RATE 300 – 19,200 bps
TRANSMIT
TIME DELAY Programmable 0 to 4999 ms
This is the time the scanner will wait for a slave to respond before sending
another request on the bus. This value should be greater than 100 ms to avoid
collisions on the bus.
DATA 8 bits (1 start bit, 1 or 2 stop bits)
PARITY Even, Odd, or None with 1 or 2 stop bits
BYTE-TO-BYTE
TIMEOUT 0.01 – 2.54 second
TURN AROUND
DELAY Less than 2 ms (fixed)

General
INPUT/OUTPUT Modbus RTU over RS-485, Two analog inputs (4-20 mA,
±10 V)
DISPLAY Upper display: 0.60" (15 mm) high, red LEDs
Lower display: 0.46" (12 mm) high, red LEDs
6 digits each (-99999 to 999999), with lead zero blanking
DISPLAY
INTENSITY Eight user selectable intensity levels
OVERRANGE Values greater than 999999 cause the display to flash 999999
UNDERRANGE Values less than -99999 cause the display to flash -99999
PROGRAMMING
METHODS Four front panel buttons, digital inputs, PC and ScanView software, Modbus
registers, or cloning using Copy function.
MAX/MIN
DISPLAY Max/min readings are stored until reset by the user or when power to the
scanner is turned off. User can reset by front panel pushbuttons, digital input, or
via Modbus registers.
PASSWORD Three programmable passwords restrict modification of programmed settings.
Pass 1: Allows use of function keys and digital inputs
Pass 2: Allows use of function keys, digital inputs and editing set/reset points
Pass 3: Restricts all programming, function keys, and digital inputs.
F4 DIGITAL INPUT
CONTACTS 50k ohm pull-up to 3.3 VDC.
Connect normally open contacts across F4 to COM.
F4 DIGITAL INPUT
